Question

目标：
使用Google Sheet API使用语法代码“spreadsheets.values.update”以更新当前单元格。

问题：
我使用了Google Sheet的教程（https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/update）提供的代码，但它不起作用。

我检索到错误消息：

"An unhandled exception of type 'Google.GoogleApiException' occurred in mscorlib.dll

Additional information: Google.Apis.Requests.RequestError

Request had insufficient authentication scopes. [403]

Errors [

    Message[Request had insufficient authentication scopes.] Location[ - ] Reason[forbidden] Domain[global]

]"

的信息：
*我可以使用与语法代码“spreadsheets.values.get”（https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/get）相关的Oath 2.0身份验证，并且它运行良好。
*“spreadsheets.values.get”中使用的Oath 2.0的相同代码效果很好 *当我用于“获取”和“更新”时，它是相同的身份验证。它适用于“获取”，但不适用于“更新”。

谢谢！

Answer 1

删除新的FileDataStore

        credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
            GoogleClientSecrets.Load(stream).Secrets,
            Scopes,
            "user",
            CancellationToken.None //,
                                   //new FileDataStore(credPath, true)
            ).Result;

Answer 2

更新需要以下授权范围

https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/drive.file https://www.googleapis.com/auth/spreadsheets

请参阅here

尝试修改数组中的范围，并在Google控制台的OAuth consent screen中更新应用程序/项目的权限，并在其中添加这些范围。

Answer 3

替换此行：

static string[] Scopes = { SheetsService.Scope.Spreadsheets.ReadOnly };

与此：

static string[] Scopes = { SheetsService.Scope.Spreadsheets };

如果未通过，请删除（token.json）文件夹，然后重试

与语法“更新”相关的身份验证范围不足
